In the proposed research is produced and tested performance of electromagnetic fuel saver. Purpose of the considered work is to research effect of varying of core of electromagnetic fuel saver to the performance of the internal combustion diesel engine. Materials for core of electromagnetic fuel saver are made of plain steel and copper. Diameters of the wire winding, which is used in the research, are 0.25 mm and 0.35 mm. Speed of the engine, and number of coil which is coiled in the winding core of the fuel saver are chosen as the testing variables. The produced fuel saver is tested in the laboratory and on the road in the traffic jam condition and in the highway. Measured variables in the laboratory is specific fuel consumption, but measured variable for road testing is fuel consumption. From this research is obtained that the performance of the electromagnetic fuel saver which use copper core is better than the electromagnetic fue

Various economical and ecological consequences of the air pollution affect animals, plants, food hygiene and human health. One of the most endangered components of the environment is the air. Elevated anthropogenic SO2 emissions can also have negative influences upon the human health, environmental conditions, and ecosystems. Monitoring of the air pollution is thus extremely important. The most emissions come from industry, heavy traffic, emissions and population density. Submitted work includes the summary of the sulphur dioxide pollution and its impact on the environment in the area of chemical factory Duslo Šaľa, Inc. Monitoring anthropic impacts helps us to predict what requirements on space particular industry requires and how they act in the area. The basis of our evaluation was observing diversity monitoring and types of negative anthropogenic features in monitored area: concentrations of SO2 in air, real sources of air pollution from the vehicles and other mechanisms and real sources of air pollution from local town residential area sources.

Mediated class relations and method calls as a confounding factor on coupling and cohesion metrics to assess the fault proneness of object oriented software is evaluated and proposed new cohesion and coupling metrics labeled as mediated cohesion (MCH) and mediated coupling (MCO) proposed. These measures differ from the majority of established metrics in two respects: they reflect the degree to which entities are coupled or resemble each other, and they take account of mediated relations in couplings or similarities. An empirical comparison of the new measures with eight established metrics is described. The new measures are shown to be consistently superior at measure the fault proneness.

The advent of HIV/AIDS has brought severe health challenges to the population and has added to the problem of health care. More case loads are entering the hospitals as new cases of infected persons are reported. It is necessary to look at the salient risk factors which are often neglected and disregarded. The study was carried out in two urban and rural settings of Cross River and Akwa Ibom States of Nigeria. The population of the study was 500 respondents randomly sampled. The results indicated that, Global System of Mobil Telecommunication (GSM) facilitate networking of people within the population. The respondents agreed that this networking often resulted in illicit sexual behaviour which serves as a primary source of contracting HIV/AIDS. The strong opinion of the research is that, there is need to carryout education among the populace on a more positive use of GSM facility. The education are to be directed on youths within the population for behaviour modification on the use of GSM facility.

This study examined the congruency between extension professionals and farmers regarding their perceptions of privatization and commercialization of agricultural extension services. The study was carried out in Delta State, Nigeria and it had a sample size of 224 respondents comprising of 134 extension professionals of the Delta State Agricultural Programme (DTADP) and 90 farmers that were randomly selected. Data for the study were collected from the respondents through the use of validated questionnaire and interview schedule. The questionnaire was used for the extension professionals, while the interview schedule was used for the farmers. Spearman’s rank order correlation coefficient was used to determine the congruency in perceptions of respondents. Results of the study showed a high congruency between extension professionals’ perception and their estimate of farmers’ perception (rho = 0.92), while the congruency between farmers’ perception and their estimate of extension professionals’ perception was low (rho = 0.08). The study recommends that farmers’ knowledge of issues relating to P and C should be enhanced through seminars and workshops organized by the appropriate extension agency.

This study examined constraints to the implementation of climate change adaptation measures by farmers in Delta North Agricultural Zone of Delta State, Nigeria. Crop farmers in three purposively selected extension blocks served as respondents of the study. A sample of 321 respondents was used for the study. A list of farmers in contact with extension served as sampling frame. Data for the study were collected from the respondents of the study through the use of a detailed, carefully designed and validated interview schedule. Trained field assistants selected in each location in addition to the researchers collected the data for the study. Data generated by the study were analyzed using descriptive statistics. Results show that there were more male crop farmers in the area of study. Also, majority (92%) of the respondents had formal education and many years of farming experience. The study found that respondents were using some adaptation measures which include: the use of crop rotation, use of sandbags at river banks, use of bamboo stakes, planting of cover crops and the construction of drainages.

Employees are considered as the human capital of any organization. If employees are motivated and satisfied they will perform their duties diligently and actively. In this research article, data of 186 employees working in Pharmaceutical industry is analyzed. The results indicated gender-wise and age-wise comparison of motivation & satisfaction of employees with respect to salary and position. Hypotheses developed to find relationship between financial rewards, motivation and satisfaction of employees. A positive relationship found between financial rewards, motivation and satisfaction. Overall results indicate employees working in Pharmaceutical industry are being offered good financial rewards. They are motivation in performing their duties and satisfied with their salary and job position.

Inconels 792 are nickel-base superalloy material that has high strength and creep resistance at temperature near their melting point. This material is commonly used in aircraft gas turbine (jet) engines, where parts or components are subjected to high temperature and high stress. Not-withstanding the high-temperature capabilities of the alloys, during service the parts are often damaged by hot gas erosion and other types of mechanism. Welding is one of the repair method available nowadays. The application is typically accomplished by Gas Tungsten Arc Welding (GTAW). Unfortunately, however, these superalloys also have limited ductilities at elevated temperatures, and are consequently subject to cracking due to differential thermal strains in some temperature ranges, a phenomenon termed “strain-age” cracking. The solution proposed is Superalloy Welding at Elevated Temperature (SWET). Elevating temperature on the parts or components that are to be welded probably could reduce the thermal gradient occurred, thus creating a crack-free weldments. Also elevated temperature could reduce the amperage needed to achieve the welding temperature, hence lower electricity and cost are resulted.

The polytechnic as of today is not aware of energy efficiency and management measures but has the capability of at least saving 230.1 gallons of diesel per day. In other to further increase conservation capacity considering the economic and environmental benefits, this paper contains verifiable data to show that energy consumption capacity can be reduced by 70 percent if conservation measures are properly implemented hence reducing wastes and drastically saving cost that could be used in solving numerous needs of both staff and students.

In this paper we have established certain indefinite integrals involving Harmonic number and Lucas Polynomials. The results represent here are assume to be new.
